In this paper, wave modes are modeled for a countercurrent flow of vertically falling liquid film and turbulent gas. In the case of small Reynolds numbers for long wave perturbations, the problem is reduced to a nonlinear integro-differential equation for the film thickness deviation from the undisturbed level. Solutions of this model equation are studied. Several typical scenarios for the evolution of periodic perturbations are presented.
